?? At most we'd need to rebuild the starship. That still is a lot less
material than the fuel. Actually we'd need much less than the whole
starship. Likely most mass of the ship (engine structure, shield, hull,
wall) does not need to be rebuild. That fraction of the mass left could be
stored in a refined but raw form onboard the ship. So not much mining would
(BTW the heavy parts likely are metal, I believe metals can be quite easely
